Daniel said my example is ridiculously complex. That's true. Where it
would apply is to nested OBJECTs. The IMG might be a default for an
image, rather than a wrapper OBJECT.
I would prefer to push for OBJECT anyway. If LONGDESC is recommended
practise for the future, D-link will continue to suffer. Since there is
no real alternative in any UA so far, that seems unacceptable in the
short to medium term.
Daniel also thought we should drop the idea of using PARAM to provide a
D-link/LONGDESC for OBJECT. I disagree. OBJECT is in such a prototype
state at the moment that it we could implement it with very little legacy
implication (by contrast to the LONGDESC/D-link case). And as an
historian, I too like PARAM better than A REL="longdesc"
